.To all whom it may concern: v

Be it known that I, JOSEPH V. Ronnsson, a citizen of the United States, and resident of Santa Monica, county of Los Angeles,

State of a California, formerlyof Chevy construction greatly expedites the renewal ofdefe'ctive hose and rovidesa convenient, simple means for cl? change of cars'du'ring the period oftransition. 1 V y To-this end my invention consists in the combinations, improvements and constructions hereinafter described, pointed out in the appended claims, and illustrated in the accompanying drawings, in which:

Figure 1 is a. side elevation ofmy improvement; v

Figure 2 is a view similar to Figure '1,

showing, my improved means of connecting the hose of a car to the automatic connector,

connected to the interchange device for coupling a car not'equipped with the connector to a car having it;

Figure '5 is a view similar to Figure 4 but shows my improved means for "connect- 7. ing the hose of a car to the connector, coupied to the head 23 of my improved interchange device. In this viewthe latch for locking theselmembers together is shown in the service position;

Figure 6 is an end view of .my improved interchange coupling. In this view the head of the coupling is omitted, and

Figure 7 is an-end view of the member 15 of my'ii'nproved means for connecting the hose of a car to the connector and to the head 23 of; the interchange device..

' Referring to the drawings: My improved sitions required in service.

ecting efiicient inter- 7 member 15 1 carried b 17 for receiving a suitable automatic To couple the hose 16 dated November 1917. $eria1 No. 866,825, filed October 15, 1914. Application for reissue filed October so, 1919. Serial No. 334,567;

connector head A .is shown mounted upon a support B which yieldably'supports the head, allowing it to move to the various po- Any satisfactory form of such support may, of course, be used with the connector head and any suitable form of connection for'the support to the-car may be employed, such as a hanger 8 to which thebase C- of the support is connected as by bolts 9. a My improved means for' connecting the hose of a car equipped with the automatic connector to the conduit 10 of the support B and for effecting eflicient interchange between a car so equlppedand one having the present hand system comprises a male member 11- suitably connected to the conduit 10 as by threads, and provided with a Hat corrugated'face 12 and oppositely disposed adapted to interlock or normally rest behind'complementary lugs 14 of a female v the train pipe hose 16 of the car. Said emale, member is provided with a circumferential seat or groove gasket or sealing device 18, the bottom of the seat beingcorrugated, as shown to give a better joint.

The gasket 18 is U shaped in-cross section and hollowed out as at 18 to allow the fluid within the conduit 10 to expand the gasket Y axially .of the hose 16 into tight engage ment with the seat 17 in the member 15 and the face 12 of the member 11, which last member is positioned in the conduit 10 so that the hose lfi'must be twistedto bring the lugs 14 into position to pass between the lugs 13 of the member 11. When the twist of the hose is spent or let out, the, lugs 14 rotate behind the lugs 13 in whichposition they are maintained by the torsional resistance of the hose 16, insuring against accidental disconnection ofthe parts. See particularly Figures 4 and 5.

communication with the hose of a car not equipped with the automatic connector, it is disconnected from the member 11 by rotatinto interchange ing it to the right or left andshifting it axially of such member 11 and is then connected to a dummy or interchange coupling1 D in the same manner that it is connecte to the member 11, after which connection to' the hose 19 of the 'u'nequippg car is ve l effected in the fashion now uni Figure 4 illustrates part-icu ploye'd; that is to'say, the head 20 of the coupling D is connected with-a like head 21 in t e end of the hose 19. The interchange coupling comprises said head 20, a suitable shank 22 made of any suitable material and a head 23 correspondlng to the member 11 in the conduit 10.- A spring, latch or look 24 surrounds the shank of the coupling D, extends through an annular flange 25 of the head 23 and servesto: lock the coupling D to the'member 15, insuring against accidental loss thereof. Figures 3 to? clearly illustrate the construction of the f'oint and'lock.

ariy the construction of the male member 11 which is connected to the conduit 10 as by threads. I prefer to carry the coupling D separately of the automatic connector and use it interchangeably with a number of connectors, though I am aware that 'it may be otherwise carried if desired, such as connected permanently with the connector.

--By the foregoing construction I have produced a simple and eflicient common means 'for connecting the base of a car to an automatic connector or to an interchange device, in such wise that the joint at the point of such connection is sealed, or the tightness thereof augmented, by the pressure of the fluid ,within said hose and said joint, whereby efficient connection of said hose to an.

automatic connector or to the hose of a car not equi ped with the automatic device, may be readi y attained.

Having thusdescribed my said invention, what 'I claim as new and desire to secure by United States Letters Patent is:

1. In an automatic train pipe connector, the combination of a coupling head, a conduit leading from said head, a hose for conductingpressure fluid, means forconne'c-ting said hose to said conduit so as to provide a substantially straight passage for the flow of pressure fluid rom one of said parts to the other, an interchange coupling land means for connectin said coupling and hose so as to provide a su tantially straight passage for the flow of pressure fluid from one of said last named parts to the other.

2. In an automatic train pipe connector, the combination of a couplin head, a con-. duit leading from said hea a .hose for conducting pressure fluid, means for con-- necting said .hose to said conduit so as to provide a substantially straight passage for the flow of pressure fluid irom one of said parts to the other, an interchange coupling, means for connecting one end of said coupli to said hose so as toprovide a substantmlly straight passage for the fiow' of pressure fluid from one of said last named parts to "the other, and means for connecting the other end of said interchange coupling to r the hose of a car not equipped with an automatic connector.

3. In an "automatic train pipe connector,

a. In an automatic train pipe connector,

6. A mechanism of the kind described comprising, in combination, an automatic tram pipe connector applied to a car, said connector including a coupling head hav-' ing a conduit, a hose on said car,- an

hose to said conduit or saidinterchange coupling so as to provide a substantially straight passage for the 'flow of pressure fluid from said hose to said conduit or coupling and vice versa, said means comprising a member connected with said hose and provided with projections adapted to cooperate with complementary projections on said conduit and said interchange coupling.

7. In an automatic train pipe connector,

the combination of a coupling head, a conduit leading from said head and carrying op positely disposed projections, an interchange coupling ada ted to connect with a similar coupling of t e hose of a car not equipped with said automatic connector and having duit or to one end of said interchange coupling so as to' provide a substantially interchange coupling formed separate from said hose, ,and means to connect said also oppositely disposed projections, a hose the combination of a coupling head, a conduit leading from said head and carrying oppositely disposed projections, an interchange coupling adapted to connect with a similar coupling of the hose of a car not equipped with said automatic connector and.

having also oppositely disposed projections, a hose normally disconnected from said interchange coupling, a member mounted in said hose and provided with oppositely disposed radially extending projections adapted to interlock with the projections either of said conduit or-said interchange coupling,

whereby said hose is adapted to be connected interchangeably with said conduit and said interchange coupling, said projections when interlocked serving to hold said hose in position to provide a substantially straight passage for the flow of pressure fluid from said hose to said conduit or said coupling and vice versa, and a packing for sealin thejoint between said member .and said interchange coupling.

9. In an automatic train pipe connector,
